Numerical data from a plurality of meters is read at a distance by reading devices installed on the meters which scan the counter dials, producing electric signals which are transmitted to' a common recorder at a central station, a group of meters being selected by a signal from the central station and the meters in the group being selected in turn by selector switches. A group of meters may consist of three sets (1, 2, 3, Fig. 1, not shown) each being, for example, a block of flats. The central station (22) contains a recorder (24). To read any such group of meters the appropriate number is dialled to select a line (19) over the public telephone exchange (20). When line (19) is energized the selector switch (7) begins to step, connecting to each of the meters (A-H) in turn. In the ninth position it transfers to the next selector switch and so on. Meter-reading.-When one of the meter lines is connected, the reader begins to read the digits displayed by the numeral wheels. For this purpose a lamp (33), Fig. 3 (not shown), is switched on and light is reflected by a mirror (40) on to the digit wheels which are to be read. The images of the numeral wheels are scanned across a shaped mask by a rotating mirror (42) having a number of mirror facets. Light passing through the mask is reflected by a second mirror (41) and received by photo-cells (37). The signals pass back to the central station and are recorded. The meter dials also bear meter identifying marks (S, T).

Abstract: 807,193. Electric measuring systems. SPERRY GYROSCOPE CO. Ltd. Feb. 26, 1957 [March 2, 1956], No. 6725/56. Drawings to Specification. Class 40 (1). In an acceleration, inclination or weightmeasuring instrument, three mutually perpendicular sensitive elements are mounted in a housing together with electromagnetic restoring devices, the current through which is a measure of the disturbing force. Each element consists of a metal rod, supported at the ends by ligaments which exert a negligible restoring force for small longitudinal displacements. Each element carries at its ends a differential condenser element. The latter are connected in an A.C. bridge circuit, the output of which, corresponding to element displacement, is applied to a restoring coil at each end of the element, reacting with a permanent magnet, to return the element to its rest position. To compensate for the effect of the restoring coil on the permanent magnet, a further coil, in series with the restoring coil is mounted round the magnet. Airgap changes due to temperature variations are compensated for. Specifications 804,847 and 804,849 are referred to.

R÷ntgen-ray tubes; vacuum tubes. - Parts between which there is a very high potential difference are connected to each other by a wall consisting of insulating sections alternating with one or more conducting sections. The potential difference may be equally divided between the insulating sections. In an X-ray tube for, say, 200,000 volts or more, the container may consist of glass tubes 1, 7 sealed to an intermediate chrome-iron cylinder 6 and carrying re-entrant tubes 2, 8 sealed respectively to the water-cooled anti-cathode 3 and to a metal shield 10 surrounding a filament cathode 11. These electrodes are situated within the metal portion 6 of the container. The anti-cathode 3 is of chrome-iron, with an inlaid tungsten plate 4. It is surrounded by a metal bell 18 to protect the joints of the envelope. An aperture 17 in the shield 10 allows passage of electrons and of the X-rays, which pass out through a window 9 closing the interior of the re-entrant tube 8. Connections 12 to the filament pass through silica beads in the metal shield 10 and are sealed through the glass tube 7. A separate leading-in wire 16 allows of impressing on the shield 10 a potential equal to the average cathode potential, or slightly lower than that of any part of the cathode. The metallic part 6 of the container is connected to earth and to the mid-point of the secondary of a transformer 23 supplying the electrodes. Variable resistances 21, 26 are provided in the primary circuits of the supply transformers. In modifications, a dome-shaped window for X-rays is sealed to an aperture in the side of the metal section of the envelope. The active surface of the anti-cathode, and the axis of the metal shield, may then be at right-angles to the positions shown, or the anticathode may have a bevelled end, the cathode being provided with a Coolidge focusing-ring. X-ray tubes of the kind described may be very highly exhausted, or may contain hydrogen or helium at a pressure such that harmful positive ionization does not occur. Such pressure may be about 0.0006 mm. of mercury, and in the case of helium may be 0.01 mm. Specifications 207,262, 208,108, and 209,833 are referred to.

Abstract: 497,088. Grinding and polishing glass. PILKINGTON BROS., Ltd., WALDRON, F. B., and SLOCOMBE, F. E. March 10, 1937, No. 7100. [Class 60] [Also in Group XXXV] In a machine for grinding and polishing glass strip on both faces simultaneously, by means of opposed tools, the tools are carried on frames slidable transversely of the strip, the frames being moved equally when the strip, due to its not being straight laterally, deviates from the central position by more than a predetermined amount. The glass 1 is treated by tools 2 rotatably mounted in frames 5, the upper frame being carried by a frame 6 and the lower frame by a frame 7. The frames 6, 7 are slidable transversely on slides 11, 12 respectively mounted on the machine frame 8, and are moved respectively by screws 15, 16 engaging nuts 13, 14 on the frames 6, 7. The screws are all geared together, so as to turn at the same speed, by bevel gearing 17 ... 24, and may be turned manually by rotation of the shaft 20, or automatically by an electric motor 25 mounted on the machine frame. The motor is controlled by a reversing- switch 40 mounted on the frame 6, and having its actuating arm 39 operated, through levers and linkage 30 ... 38 by a roller 29 which is pressed against the cut edge of the strip 1; since the frame 6 carries the switch 40, this also moves transversely until the arm 39 breaks the motor circuit. The arm 39 is given play in the actuating-fork 38 so that small movements of the strip can occur without causing movement of the tools. In a modification, two switch arms engaging respectively staggered sets of contacts are provided, one arm being moved by the strip to close the motor circuit and the other being moved by the motor to open its circuit ; a reversing-switch actuated by an arm carried friction tight on the spindle of the switch arm moved by the strip serves to drive the motor in the required direction. The devices for indicating the position of the centre line of the strip described in Specification 497,087 may be employed to effect the movement of the tools.
